Initial post-operational reports indicate the small arms fire originated from an Afghan National Army combat outpost, and the subsequent air support called by the joint force likely killed at least four ANA soldiers.
"We work extremely hard to coordinate and synchronize our operations. This is a regrettable incident and our thoughts go out to the families of those killed and wounded," said Brig Gen. Eric Tremblay, ISAF Spokesperson.
"As stated in the Afghan Ministry of Defence news release issued earlier today, ISAF and ANA will conduct a joint investigation to determine the facts and circumstances of this unfortunate incident," said MOD spokesman Gen. Azimi.
